ServerCapabilities

data class ServerCapabilities(val tools: ServerCapabilities.Tools? = null, val resources: ServerCapabilities.Resources? = null, val prompts: ServerCapabilities.Prompts? = null, val logging: JsonObject? = null, val completions: JsonObject? = null, val experimental: JsonObject? = null, val extensions: Map<String, JsonObject>? = null)(source)

Capabilities that a server may support.

Known capabilities are defined here, but this is not a closed set: any server can define its own additional capabilities through the experimental field.

The presence of a capability object (non-null value) indicates that the server supports that capability.
